The National Institute for Occupational Safety and Health (NIOSH) Pittsburgh Research Laboratory (PRL) participated in an experiment to facilitate the remote control of dozers used on coal stockpiles. The experiment consisted of supplementing the normal sensory cues an operator requires to manipulate the dozer from a remote location. NIOSH provided and tested a vision systems intended to give the operator the ability to operate the dozer safely and efficiently from a remote position. This paper highlights the genesis of the experiment, identifies the contributions of Consol Energy and Caterpillar, and details the NIOSH efforts and successful test results.

Fault tree analysis is a systematic safety analysis tool that proceeds deductively from the occurrence of an undesired event (accident) to the identification of the root causes of that event. One recurring mine safety problem—a dozer falling into a...

"This study was done to evaluate the costs of various dumping operations at waste and spoil piles. It has been the theorized that accidents associated with dumping operations might be reduced by short-dumping rather than edge-dumping, but many operat...

"This report describes serious injuries occurring to bulldozer operators working at U.S. coal, metal, and nonmetal mines. The period covered is 1988-97. The data were collected by the Mine Safety and Health Administration (MSHA). A total of 873 injur...

Dump site injuries occur in all major mineral industries. Working in elevated areas near an edge is a common hazard for operators of off-highway mobile mining equipment. In this Information Circular (IC), serious injuries involving haulage trucks wor...
